Hi Hal,

I asked a similar question a bit ago. The plans for both seem fairly simple
and straight forward. I'm trying to decide if I should just buy one or not.
The DIY one's don't seem to require much investment, but I worry that they
may not work effectively, either in filtering or backwashing. Anyway, I'm
still investigating.

I guess you are the one who got me started looking.

I have the same problems, however the ready made with similar size and
function would cost at least $1000 or more, above the cost of my
making one.

I've seen a Nexus set up and working and if I were looking for a high
dollar filter for high dollar fish that is what I would consider. It
uses air bubbles to agitate the beads, most of the others I've looked
at use backwash.

Regards,

Hal
